结果讯息：

Exception calling "Substring" with "2" argument(s): "Length cannot be less than

At line:1 char:19
+ gc .\dict.txt | %{$_.Substring(0,$_.IndexOf('/'))} | Out-File -Encodi ...

如果您只想从文件的每一行末尾删除/和某个字符并输出到新文件：

Get-Content dict.txt | ForEach-Object {
  $_ -replace '/.$',''
} | Out-File list.txt -Encoding UTF8
